## How to Convert Electronvolts to Watt-seconds

To convert an electronvolt measurement to a watt-second measurement, divide the energy by the conversion ratio. One watt-second is equal to 6.2415E+18 electronvolts, so use this simple formula to convert:

The energy in watt-seconds is equal to the electronvolts divided by 6.2415E+18.

**For example,**here's how to convert 5.0E+18 electronvolts to watt-seconds using the formula above.

Electronvolts and watt-seconds are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Electronvolts

The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as *eV*, for example 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.

## Watt-seconds

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds are usually abbreviated as *Ws*, although the formally adopted expression is *W·s*. The abbreviation *W s* is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}
